Using the high-performance liquid chromatography (HPLC) and liquid chromatography mass spectrometry (LC-MS) analysis, mono-methyl phthalate (MMP) and phthalic acid (PA) were detected as the major intermediates of DMP biodegradation. When combined with the determination of chemical oxygen demand (COD...
Therefore, tattoo composition is frequently unknown for the consumer since labelling on these samples is generally non-existent, and in addition, hazardous chemicals such as phthalate esters, aromatic amines, heavy metals or even adhesive substances, which may lead to skin irritation, can be still ...

The strong base and acid solutions were standardized using primary standards such as potassium hydrogen phthalate (Sigma-Aldrich, Milan, Italy) and anhydrous sodium carbonate (Fluka, Darmstadt, Germany), previously dried in an oven at T = 383.15 K for 2 h. Since NaOH is photosensitive, ...
